Treat database field as a flat file source

We have a partner sending us csv data to a web service of ours that gets sent to a messaging system that is SQL Server based.

I am writing data to disk and then importing to another database by using this file as a flat file source in an SSIS Data Flow task.

Although this works I'd like to avoid using the file system and treat the database field as a flat file source.

Is this possible?

I'm very new to SSIS packages and searching for this scenario is very difficult because of the number of hits just relating to importing a csv file.
